B1653Driver seat position sensor circuit fault

  • Toyota/Lexus code · Airbag (SRS)
  • Lights a warning lamp
How the car detects it
The sensor that tells the airbag unit whether the driver's seat is far forward has a fault; the unit uses it to adapt how the driver airbag deploys. While an airbag fault is stored, the affected airbag or pretensioner may not deploy in a crash. Have it repaired before relying on it. Never probe airbag connectors with a meter: that can fire the airbag.
